Quality is excellent. -shortest length is still too largeoverall a good headset, but i have returned mine as it would not fit correctly at the shortest length options. A malinquore le sto rendendo, perche? Premetto che tempo fa presi le precedenti Px e dovetti renderle perché perdevano facilmente il sigillo dei padiglioni con conseguente drastico calo delle prestazioni audio con bassi azzerati (suono "scatolato" orribile) e siccome io porto gli occhiali, anche questa condizione comporta quel problema, erano non adatte a me. You will hear details and nuances in the music that budget earphones miss and the whole soundscape is open and natural; very impressive from an in-ear product. I did get a little black lint from the beanie but nothing to cause damage. If you are expecting an OEM version of the samsung earphones, do not get this item. I have used this literally EVERY DAY since I bought it. the ALLEN BOLT nuts. Definitely a must have if you need comfort. I have a slight concern because it gets hot.
